Giving a host access to a NFS share

Hi Dee,

we always follow this procedure:
- issue a server_export server_2 -P nfs -list to get current exports for the filesystem
- copy the ro=, rw=, root=, access= components to another terminal / notepad...
- add the new host to the ro=/rw= lines as needed
- type the server_export command and copy+paste the ro/rw.. components into it

Yeah that's what we're doing too. I was hoping there was an easier, less error prone way to do this.

Anyone have an idea?

You can use netgroups, and modify the netgroup file offline, which might help maintain the integrity of the access list. You can then make changes to the netgroup file without changing your export at all; just upload a new copy of the netgroup file.

Hmmm....not a bad idea but I don't know that I really wanna use a netgroup. Any other ideas?

You don't have to use NIS with a netgroup file;) And you can use subversion or another tool to kepp track of changes. Easy to script too.

ps. - I do not have a NIS environment, just many standalone hosts. -John

Can someone give an example of using a netgroup file ?

i.e. host entry format, location, applying

Does the file live under nasadmin somewhere ?

If you dont have NIS the netgroup file has to be copied to the data mover using server_file as described in the Naming services manual.

Here's what it says about the format:

Create or edit a netgroup file

Each line of the netgroup file defines a group and has the format:
groupname member1 member2 ...

Each member is either the name of another group or indicates specific hosts, users,
and domains, referred to as a triple, as follows:
(hostname,username,domainname)

Any of the triple¿s three fields can be blank, meaning all the values in that field are
included. A dash in any of the fields means there are no valid values. For
example, the following line defines a group called ouruniverse that consists of all
hosts and users in the NIS domain ourdomain.
ouruniverse (,,ourdomain)

The following lines define a group called ourhosts that includes all of the hosts but
none of the users in the domain, and a group called ourusers that includes all users
but no hosts.
ourhosts (,-,ourdomain)
ourusers (-,,ourdomain)

A netgroup file can include as many lines as required; however, each line must be
less than 1 KB in length. If necessary, a line can be continued on another line by
using the backslash (\) as a continuation character. A triple, however, cannot be
split across two lines.

Note: If you use a backslash (\) as a continuation character, it must be the last character on the line. It cannot be followed by spaces.
